Diagnostic information
Non-safe diagnostic information about the statuses inside the safe sensor cascade and
about the Flexi Loop nodes is also sent to the Flexi Soft safety controller.
Further processing of information in the logic editor
The safety information and the non-safe diagnostic information can undergo further
processing in the logic of the Flexi Soft safety controller (see the “Flexi Loop in the Flexi
Soft Designer” operating instructions, part no. 8014522) or it can be forwarded to a
PLC, for example, via a gateway.
